Dupont Circle's Deckover Is Finally Taking Shape: How Fall Weekends Work Around It

"The big big news is the first deckover concrete pour will take place tonight." That's how DDOT's project log opened on September 17, 2026, with the underpass lanes closed from 8 p.m. to 5 a.m. for the work. Nine days later the crews had poured spans 1 and 3 of the plaza's five spans. More than 20 concrete trucks were scheduled in and out for that first night. Spans 2 and 4 were set for the evening of September 26, and span 5 was planned for the week of September 28.

As of this weekend, DDOT hasn't posted anything confirming that the last pour happened. Either way, the work is about to change shape. Most of the heavy deckover work so far has happened in the middle of Connecticut Avenue, over the traffic lanes, on overnight closures. The next phase is daytime work on the service lanes and sidewalks, directly in front of the stores. That changes where Dupont's fall weekend happens.

The Slab Is Down. The Sidewalks Are Next.

DDOT has described this sequence for months. All 49 girders were in place by July 23, ahead of schedule, and the project passed its halfway point in June. The September 17 update said the next step: "Once the three pours are complete, crews will begin work on the service lanes and sidewalks in the 1500 block."

The 1500 block is home to Kramers at 1517 Connecticut Avenue, with JF Books at 1509 and Connecticut Ave Wine & Liquor at 1529. One block north, the 1600 block's northbound side already looks like the 1500 block will soon. Pedestrians walk in a protected lane out in the street while crews lay new sidewalk and pavers, and ramps lead from that lane up to the shop doors. DDOT names Comfort Shoes and Pure Green among the 1600-block businesses and says every business stays open throughout the project.

The project team met with 1500- and 1600-block merchants in mid-September, along with ANC 2B Commissioner Jeff Rueckgauer, the Dupont Circle BID and Dupont Circle Main Street, as streetscape work began on those blocks. That timing matters for these shops. In May 2026, WJLA reported that the BID found foot traffic at some businesses had dropped "by as much as 50 to 60%." Owners pointed to barriers, torn-up sidewalks, limited parking and harder deliveries and pickups. In September, the District's small business department identified independent retailers in the active 1500- and 1600-block zone for relief grants of up to $10,000 each. Applications closed September 28, and the department aims to issue payments in the first quarter of fiscal 2027.

Getting Around the Circle This Month

Here's what the closures look like this fall:

• Q Street runs one way eastbound all the way through again. Drivers heading from the Circle to 19th Street are detoured up New Hampshire Avenue and back to Connecticut via R Street.
• The northbound underpass lanes stayed open through the September sidewalk work, except for the overnight pour closures.
• The 1800 block has its own construction for the Geneva residential conversion, so some of the detour signs there belong to that project and not to DDOT's.
• The southbound side from California Street to Q Street is nearly finished. Landscaping is planned for later this fall, when planting season starts, and again in spring 2027.

DDOT still says the project is on schedule for early summer 2027, "subject to weather and unforeseen circumstances."

Where the Weekend Is Happening Instead

The plaza won't hold events until next year, and the east side of Connecticut is about to have crews on its sidewalks. Meanwhile, the fall calendar has settled into Dupont Circle Park, 20th Street and the side streets. Here's a weekend built from what's actually on the schedule:

1. First Friday, 6 to 8 p.m. The free, self-guided ArtWalk Dupont runs the first Friday of every month, with stops including the National League of American Pen Women at 1300 17th Street NW. The next one is November 6. The BID calendar also lists El Marsam, a show of modern and contemporary Egyptian art at the Middle East Institute, 1763 N Street NW, with more than 45 works.
2. Saturday, noon to 3 p.m. Music in the Circle, the BID's free concert series, plays every Saturday in Dupont Circle Park through November 7. The rest of the lineup: Tavair Dominque on October 10, Different Answers on October 17, Sadia on October 24, a Halloween & Bluegrass afternoon on October 31, and Too Much Talent on November 7.
3. Saturday night. First Round Bar & Social opened in mid-September in the old Childe Harold basement at 1610 20th Street NW. It has trivia on its schedule, karaoke on Wednesdays starting in October, and late-night programming. Two blocks west, La Merna at 2153 P Street NW serves Chicago tavern-style pizza. It previewed in early August and opened to the public on August 13. In August, the owners told Eater they planned a weekend sandwich window next door with Italian beef and hot salami, aiming for October.
4. Sunday, 8:30 a.m. to 1:30 p.m. The FRESHFARM Dupont Circle market is open year-round on 20th Street NW between Massachusetts and Connecticut Avenues, with its 2026 season running through December 27. All summer, DDOT reopened the 20th-to-Q service lane on weekends to protect what its log calls "the beloved Sunday Dupont Circle Farmer's Market."
5. Sunday, after the market. Starting October 11, the Dupont Little Flea sets up weekly at Diego's Hair Salon, 1901 Q Street NW, with vintage and antique goods and work from local makers.

One opening this week lands right in the construction zone. Dupont Barber & Spa, at 1706 Connecticut Avenue NW, holds its grand opening Thursday, October 8, from 5 to 8 p.m.

The season started with a night that showed how the neighborhood holds events while the work goes on. Dupont's Art All Night on September 12 spread across more than 15 venues with art, live music and interactive programs. DDOT congratulated the organizers in its next update.

What the Slab Is Meant to Become

DDOT describes the finished deckover as everyday space for lunch, reading and play. It also lists event uses: a farmers market, outdoor movies, music, plays and cultural events. Traffic will keep running underneath, and a pedestrian-only crossing will connect both sides of Connecticut. The BID's 2025 annual report lists concerts, movies, art markets and café seating as possibilities. The BID hired Gehl Studio to develop a programming framework for the plaza. In July, WTOP reported that the plaza would host community events and a large public-art collection.

"After nearly a year of work, it's exciting to finally see the public plaza starting to come to life."

The planting plan is still unclear. DDOT's April 2025 design drawings call for a curbless, open event space and label precast boulders, a raised planter, a bench, bike racks and one proposed tree. Washingtonian's June 2025 report said there were no plans then for permanent landscaping on the plaza. Nothing published since settles how much green the deck will have, so expect a hard-surfaced space.

Back in August, DDOT warned that "there is still months and months of work in the deckover area" after the pours: stormwater and electrical lines along the service roads, then the sidewalks. Its suggestion for anyone walking past the construction was to stop into Kramers for a good book. That advice matters most this fall, while crews are on the 1500-block sidewalks.
